Which one of the following equation correctly represents the lowering in vapour pressure due to capillaries? \) b) PK=PO exp⁡⁡\( \) c) PK=PO exp⁡⁡\( \) d) PK=PO exp⁡\( \)

Correct Answer: \frac{2\sigma v}{d_p RT}
The Kelvin equation for the lowering in vapour pressure due to capillaries is given as- PK=PO exp⁡⁡\( \)

Consider the following statements and choose the correct answer:
1. A direct proportionality exists between vapour pressure and the concentration of water vapour in the atmosphere
2. Relative humidity is an expression of the ratio of the actual vapour pressure of the atmosphere when saturated at the same temperature
3. A rise or fall in temperature with no change in vapour pressure will cause a drop or rise, respectively, in relative humidity
4. A rise or fall in vapour pressure with no change in temperature will be accompanied by a rise or fall, respectively, in relative humidity

Consider an ideal vapour-liquid binary mixture, find the total pressure if the vapour pressure of A is 260 mmHg and the vapour pressure of B is 520 mmHg and the composition of A in mole fraction is 0.55.

Which of the following expressions represent the Fermi probability function? /KT) b) fF(E)=exp(-/KT) c) fF(E)=exp(/KT) d) fF(E)=exp(-/KT)

A vessel of volume 1000 m3 contains air which is saturated with water vapour. The total pressure and temperature are 100 kPa and 20°C respectively. Assuming that the vapour pressure of water at 20°C is 2.34 kPa, the amount of water vapour (in kg) in the vessel is approximately

You use Visual Studio .NET to create a Windows-based application. The application includes a form named XYZProcedures (EXP). EXP allows users to enter very lengthy text into a database. When users click the Print button located on EXP, this text must be printed by the default printer. You implement the printing functionality by using the native .NET System Class Libraries with all default settings. Users report that only the first page of the text is being printed. How should you correct this problem?
